JOHN D. JONES, 0F WALLA WALLA, WASHINGTON, ASSIGNOR TO THE LUBRIGATING WHEEL AND ROLLER COMPANY, OF WALLA \UALLA, WASHINGTON.

LUBRICATING DRAPER-ROLLER.

Specification of Letters Patent.

Patented Dec. 7, 1909.

Application filed September 19, 1908. Serial No. 453,765.

To all whom it may concern:

Be it known that I, JOHN D. Jones, a citizen of the United States, residing at Walla \Valla, in the county of lValla lValla and State of Vashington, have invented a new and useful Lubricating Draper-holler, of which the following is a specification.

The objects of the invention are, the provision in a merchantable form, of a device of the above mentioned class, which shall be inexpensive in construction, facile in operation, and devoid of complicated parts; other objects being made manifest, hereinafter, as the description of the invention progresses.

The invention consists in the novel construction and arrangement of parts hereinafter described, delineated in the accompanying drawing, and particularly pointed out in the appended claims, it being understood that divers changes in the form, proportions, size and minor details of the struc ture may be made without departing from the spirit or sacrificing any of the advantages of the invention.

Similar numerals of reference are employed to indicate corresponding parts throughout the accompanying drawings.

In the accompanying drawings, Figure 1 shows my invention in longitudinal section Fig. 2 shows one end of my inventionin 'longitudinal section, the same being enlarged, that the details may more clearly appear.

The form of roller herein described is one of that general type which is adapted to'be used on grain headers, threshers, grain feeders, straw-carriers, grain belts, and for all purposes where an idle roller, so-called, is necessary.

In my invention I provide a tubular roller 1, within which are inclosed oil-cups 2, the said oil-cups being rigidly secured to the terminals of the tubular roller 1. The oilcups 2 are preferably cylindrical in form, and comprise a base portion 6 and a body portion 7, the body portion lying without the base portion, being coaxial therewith, and of smaller diameter than the base portion. A shoulder 9 projects inward from the periphery of the oil-cups 2,. and unites the base portion 6 with the body portion 7 The ends of the oil-cups 2 are closed; from the outer end the outer bearing 4 projects inward into the interior of the oil-cups 2. This outer bearing 4 is frusto-conical in shape, and has its inner end 10 lying substantially in the plane of the shoulders 9.

The inner end of the oil cups 2 is closed and from this inner end projects out-ward the inner bearing 3.

The outer end of the oil-cups 2 is prolonged to form a flange 8 upstanding beyond the outer surface of the roller 1. The roller 1 is rigidly connected to the base portion 6, and a suitable inlet valve 5 is mounted in the oil-cup 2, the said valve being accessible through the wall of the roller. This inlet valve 5 may be of any form. Preferably, however, it includes a plug 13, upwardly pressed by a spring 14. The plug 13 may be pushed down by the nose of the oil-can and the oil allowed to pass through the inlet valve 5' into the oil-cups 2. When 'the pressure exerted by the oil-can is removed the spring 14 will force the plug 13 into its place and close the inlet valve.

WVhen the oil passes into the oil-cups through the inlet-valve 5 it falls upon the frusto-conical face 11 of the outer bearing 4 and is deflected into the oil-cups 2. The disposition of this outer bearing 4 is such that it tends to keep the oil from finding its way out through the end of the oil-cups 2. It is intended that the oil-cups 2 shall be filled with some porous material, preferably pure wool and it is desirable that this filling material should at all times be in a position to receive the oil as it first comes through the inlet valve 5. \Vhen once this material with which the interior of the oilcups is filled is pressed up about the inner end of the inlet valve 5, the inwardly projecting shoulder 9 will tend to keep it in its place.

Since the oil is not discharged near or about the inner ends of the oil-cups, the inner bearing 3 is made to extend outward, the protection against leakage afforded by a bearing disposed in the position assumed by the outer bearing 4, being unnecessary.

The device in its completed form is adapted to rotate as an idle or loose roller, upon a shaft designated by the numeral 12.

Having thus described my invention, what is claimed is I 1. In a device of the class described, cylindrical oil cups each comprising a base portion and a body portion integral with the base portion, the body portion extending beyond the base portion, coaxial therewith, and of smaller diameter than the base porbase portions of the oil cups.

-outer bearing carried by the base portion;

a tubular roller inclosing the oil cups and having its terminals rigidly attached to the 2. In a device of the class described, a cylindrical oil cup having a frusto-conical bearing projecting inwardly from its outer end and being provided with a shoulder projecting inwardly from its periphery in substantial alinement with the plane of the inner end of the bearing; a roller inclosing the oil cupand having its terminal rigidly attached thereto; an inlet valve for the oil cup accessible through the wall of the roller and positioned to discharge a lubricant upon the frusto-conical face of the bearing.- v 3. In a device of the class described, a cyend and having a bearin lindrical oil cup having a frusto-conical bearing projecting inwardly from its outer projecting outwardly from its inner en and being provided With a shoulder projecting inwardly from its periphery in substantial alinement with the plane of the inner end of the frusto-conical bearing; means for discharging a lubricant upon the frusto-conical face of the bearing; and a roller inclosing the oil cup and having'its-terminal rigidly attached thereto.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.

JOHN D. JONES.
